ABSTRACT:
This relates to a lock arrangement for locking together closure panels of cartons, particular cartons of the wrap around type. The lock arrangement includes a primary lock panel which carries a primary lock arrangement including a projecting primary locking tab which is disposed on one side of a semicircular cut out or aperture and wherein there is a locking ear on the opposite side of the aperture. The other closure panel, which is the inner closure panel carries a secondary lock arrangement which includes a secondary locking tab which is connected to the secondary flap along a hinge line and is separated therefrom by an offset partial cut line so as to define a locking shoulder.
When the lock arrangement is formed, the primary locking tab is locked behind a shoulder on the inner closure panel defined by the displacement of the secondary flap and the primary locking tab extends through the aperture and is locked behind the locking ear. The primary locking tabs and the secondary tabs are disposed in side by side relation with the secondary locking tab projecting generally normal to the closure panels and projecting between adjacent containers so as to hold the containers apart. The secondary flap is of a width at least equal to the overall width of the primary lock arrangement.
